So for this tank I'm using the Grimm method, i went with an Exo Terra 24x18x18 with 2 exo terra medium compact top with 6 Natural light 13W light bulbs. i gutted the top of the exo terra top so there was just the frame then i bought glass to fit in to it because i wanted to keep the tube holes in the back of the top. for water i went with the Bulk reef supply 4 stage RO/DI unit i have had RO and DI units before and there honesty is no difference but if you want to be picky well thats up to you. for misting i chose exo Terra monsoon RS 400 i have had the mist king in the past and there about the same when it comes to smaller tanks I'm my own preference.

for timer's i when with the Digital Aquatics HerpKeeper Net unit with extra power bar for up to 8 outputs for control. For fog i when with the zoo med Repti fogger and back up Repti fogger just in case because of all the fan issues i have heard about. well any ways this is what i have so far in my build.

like your pictures with the several angles..I see you have, what I assume, is a return hose for the water...is there a waterfall? Is the pump inside that one column? What is a "Windsor" screen? Two fans inside the other column?

Yes the return hose for the water goes under the egg crate to the water fall, and yea the pump is inside that one column for easy replacement. Windsor screen is a company here in windsor Ontario that makes window screen i thought it was appropriate to use the companies name. there is one fan column that has 2 air intakes from the bottom and 2 air outtakes on the top making it more push more air with out 2 fans

plants in just waiting for my jewel orchids on next Wednesday
can't seem the find any "Pumilio Oophaga" in canada or any breeders that have any but "the Cavern Tank build" was great can't wait to finish it and add more vines in to the back/ java moss later on
